Abstract
A system for treating an aneurysm includes an expandable barrier positionable to bridge an aneurysm neck. The barrier may comprise a fiber mesh, a balloon or a molly anchor member, and may unroll, unfold, or inflate from a compact configuration to an expanded configuration. Expansion of the barrier may be greater radially than axially. A vaso-occlusive member comprising a coil or balloon may be deposited in the aneurysm. Another aneurysm treatment system comprises an outer fenestrated stent and/or an inner fenestrated sleeve, which may be implanted together adjacent an aneurysm neck to regulate blood flow to the aneurysm. The sleeve may be movable relative to the stent to open or occlude the fenestrations, which may vary in size, shape, and distribution. An intra-luminal vessel occlusion device comprises a stent and a sheath. A drawstring may be actuated to gradually close a sheath orifice to control blood flow through the vessel.
